摘要:运用中断延迟的方法,测试了嵌入式Linux实时性,分析了Linux实时性弱的原因。提出了几种增强实时性的方法,介绍了在嵌入式Linux系统底层安装1个实时内核RTLinux法,即双内核法。并测试了RTLinux的实时性,发现其大为改观,改造后的嵌入式Linux系统可以满足强实时性系统的要求。
In the thesis, real-time character of embedded Linux was tested via the approach of interrupt delay, and the causes of the shortage of Linux real-time character was analyzed. Thereby, some methods of the improvement of Linux real-time character were introduced, especially the method of two kernels-setting a real-time kernel in the bottom of embedded Linux system. Furthermore, RTLinux real-time performance was tested, and its performance was very satisfactory. In short, the improved embedded Linux system displayed a very good real-time performance which could meet the requirements of the system.
